Retarding and timelimit devices; automatic circuit-breakers. -<A> time-lag device of the dash-pot type, particularly for use with electric circuit breakers comprises a pair of relatively movable parts one or both of which serves as a piston, one part being actuated directly by the applied force and the other indirectly through a spring or its equivalent and the construction or arrangement being such that relative movement of the parts causes variation of the fluid passage. In the form shown, the cylinder a is formed at its closed end with a tapered or cylindrical recess b within which is located a piston comprising two parts c, d. The part c is dished and provided with apertures e and is slidably mounted on the piston-rod h and acted upon by a spring i. The other part d is mounted rigidly on the piston-rod and is provided with apertures f and a valve g. On a small force being applied to the piston-rod h, no relative movement takes place between the parts and the fluid passes around the part c, through the apertures e, and between the parts. When the applied force is large, the resistance of the spring is wholly or in part overcome and the parts move together, restricting the fluid passage from one side of the piston to the other. The spring i, in a modification, may be replaced by a number of concentric springs of different lengths so as to come into action successively.
